Have you considered a Wiki web for documentation and guides?
The developers of Renoise introduced this system and it works really well, as the userbase all write up missing documentation and it can be revised, removed, updated etc. The users can’t change the layout, only update and add information.
It might take alot of workload off for you, and you could give permission to upload documentation to just a limited group of regular Podium users (though it goes against the Wiki tradition a bit 😉 ).
